IMPROVEMENT IN MALT HOUSES OR KILNS.

Specification forming part of Letters Patent No. 5],] 17, dated November19, 1867.

To all whom it may concern:

Be it known that 1, WILLIAM APPLETON, of the city and county of Albany,in the State of New York, have invented a new and useful Improvement inMalt Houses or Kilns, of which the following is a full, clear, and exactdescription, reference being bad to the accompanying drawings, formingpart of this specification,and in which Figure 1 represents alongitudinal sectional elevation of a malt house or kiln constructedaccording to myimprovement; Fig. 2, a transverse section through theline 00 x in Fig. 1, and Fig. 3 an end elevation of the same.

Similar letters of reference indicate corresponding parts.

In maltin g as heretofore practiced it has been customary to admit airto and regulate the temperature of the steeped barley or room in whichit is spread to heat and germinate by opening more or less windows inthe sides of said room. This method involves frequent adjustmentof suchwindows, according to the temperature or condition of the externalatmosphere, and unless great particularity is observed, whichnecessitates great loss of time and labor, an undue exposure takes placethat damages the grain or seriously interferes with the proper maltingof the barley.

The object of my invention is to remedy this defect; and the nature ofmy invention consists in a riovel arrangement of air openings and fines,whereby a constant supply of fresh air is or may be made to pass in agentle cur rent over the malt-floor by suction or draft, as induced bycommunication with the malt-kiln fire used in drying; and said inventionfurther consists, in combination with the same, in an arrangement ofother tlues opening to the external atmosphere and conducting air aboveand below the kiln-fire, for, under certain conditions or at intervals,better regulating the strength of the current above referred to andtemperature of the heating-chamber. By this my improvement the maltingprocess is ren dered more equable as regards the regulation oftemperature, much labor and particularity dispensed with, and lessexposure induced to sudden or violentand injurious changes of Wind andWeather.

Referring to the accompanying drawings, A, B, and 0 represent the floorsof a malt house or kiln, the upper floor, A, say, serving and graincontained therein; but in this my improvement they are only necessaryfor lighting purposes, and may be kept closed.

To properly ventilate this chamber by admitting a constant and gentlecurrent of fresh air to .pass over the malt-floor, and so preventcutting of the roots of the grain while germinating, I connect eitherheating-chamber F of the kiln proper by a tube or flue, G, with themalting floor or chamber '0, and establish an opening or flue, H, (anynumber, according to the number of drying chambers or kilns proper,) atthe opposite ends of said chamber 0, whereby the tire in or heat of thechamber F induces a gentle and direct current of air from the outsideover the malt-floor, which serves efi'ectually to equalize or controlthe temperature, valves or dampers, if necessary, being furnished theflues G and H. In this way the kiln-fire used in drying may be made tocontrol the temperature of the grain on the malt-floor, and of whichfire, I is the hearth; J, the drying table or surface, furnished withfeed and delivery communicationsK L; and M, the

usual or any suitable shaft for carrying 011' the gases and vaporgenerated in drying.

The heating-chamber F is or may be further provided with a check-flue,S, preferably opposite the flue G, to prevent in very cold weather thetoo sudden introduction of cold air on or to the grain on the malt-floorand serving to reduce the strength of the kiln-fire; also, for thefurther introduction of air, shouldthe same be required-to modify oreffect the current passing through the malthouse and through the flues Gand S, a covered air boxor flue, N, is arranged to conduct air from theoutside atmosphere to and through, from below, the fire of the kilnproper. These tines S and N should also be provided with regulators ordampers. This latter flue, N, will likewise answer to supply air to thefire to effect or assist combustion. Of course one, two, or more kilnsproper may be worked side by side in the one malt-house, the same beingfurnished with flues, as described.

What is here claimed, and desired to be seber F, for operation togetheras herein specicured by Letters Patent, is-- fied.

1. The induction of a current or currents of 3. The flue N, incombination with the heatair over the malt-floor by means of draft pipesing-chamber F, malt-floor (J, and flues G and or tubes G, connectingsaid floor or chamber S, for action in concert as specified.
